Phenolic metabolites of anthocyanins modulate mechanisms of endothelial function [PDF]

open access: yes, 2015
Anthocyanins are reported to have vascular bioactivity, however their mechanisms of action are largely unknown. Evidence suggests that anthocyanins modulate endothelial function, potentially by increasing nitric oxide (NO) synthesis, or enhancing NO ...

Atomic Precision CoCu Heterodimers with Pseudo‐D3h Symmetry Enable Tandem Nitrate Reduction

open access: yesAdvanced Science, EarlyView.
The Co─Cu heterodimer anchored on nitrogen‐doped graphene oxide substrate facilitates electrochemical nitrate reduction in alkaline medium. Co site promotes water dissociation to supply a proton, while Cu sites enhance nitrate adsorption and activation.

Harnessing Transformation of Metal‐Ligand Coordination in Dinuclear Ni(II)‐Schiff Base Coordination Polymer for Promoting Electrochemical Oxygen Evolution

open access: yesAdvanced Science, EarlyView.
Ni–Schiff base coordination polymer [Ni2(tmd)2]n was synthesized and applied to enhance alkaline OER by virtue of its transformation between 5‐ and 6‐coordinate Ni sites along with the spin state exchange. ABSTRACT One of the major challenges in overall water splitting is improving the sluggish kinetics of the anodic oxygen evolution reaction (OER ...

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Restructuring and Cost of Reducing NOx Emissions in Electricity Generation [PDF]

open access: yes
The U.S. electric power sector is in the midst of two major regulatory changes. One is the change from cost-of-service regulation to competition as a means of disciplining electricity prices, often referred to as “electricity restructuring.” The other is

Polydatin alleviates mitochondrial damage and apoptosis of lung epithelial cells by inhibiting toll‐like receptor 4‐dependent macrophage activation in asthma

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The alleviation of asthma by polydatin is dependent on the blockage of the toll‐like receptor 4 (TLR4)/P2X7R synergy in macrophages. The blockage of the TLR4/P2X7R synergy results in decreased release and secretion of interleukin‐1β (IL‐1β) and IL‐18. In epithelial cells, low IL‐1β and IL‐18 levels inhibit mitochondrial damage and apoptosis.
